6AN Male to 3/8in Tube Adapter Fitting

The 6AN Male to 3/8in Tube Adapter Fitting by VIBRANT PERFORMANCE is a precision hose connector engineered for high-pressure fluid systems in performance engines, fuel systems, and transmission cooling lines. This straight-configuration adapter bridges a 6 AN male port to standard 3/8-inch tubing, making it an essential component for custom fuel injection builds, turbo cooling setups, and custom hydraulic applications. Whether you're upgrading a street machine or assembling a race-ready fuel system, this fitting ensures reliable, leak-free connections under demanding conditions.

Constructed from aluminum and finished in black anodized coating, the 6AN Male to 3/8in Tube Adapter delivers corrosion resistance and weight savings critical to performance applications. The fitting features an integrated compression ferrule system that secures the 3/8-inch tubing without additional clamps, creating a sealed joint that withstands pressure spikes and vibration common in modified engines. The straight-port design minimizes flow restriction and turbulence, preserving system efficiency while the universal fit accommodates both metric and imperial tubing standards across diverse platform configurations.

Professional installers and engine builders rely on this adapter for fuel system transitions, radiator coolant circuits, and intercooler plumbing where standard NPT connections won't suffice. Installation is straightforward—the ferrule compresses around the tubing as you torque the fitting body, creating a permanent, vibration-resistant seal that requires no additional sealant tape or thread-locking compound. This single-unit fitting (each) reduces overall system complexity, lowering leak points and improving reliability across street, strip, and circuit applications.
